Title: Automatic vehicle parking time monitor and indicator - transfers vehicle clock time to display when ignition is switched off
Inventor: NILSSON WOLFGANG
IPC: G07C5/02
Filed: 1979-02-06
Abstract: A vehicle parking time monitor is applicable to vehicles fitted with electrical clocks (5). It eliminates the possibility of the driver forgetting to set the time at which he parks his car and so becoming unnecessarily liable to parking fines. The monitor operates without conscious effort on the part of the driver, i.e. it is automatically activated when the vehicle is parked. It can be used with digital or analogue clocks. A memory (4) connected both to the ignition switch and the clock transfers the time at which the ignition is switched off to an indicator visible from outside the vehicle. The indicator displays the ignition switch-off time until the ignition is switched on again, at which time both the memory and indicator are reset.

CrO3 per 100 pts. wt. wax. The process is carried out by (a) heating a portion of the chromic acid (corresp. to 50-100 pts. wt. CrO3 per 100 pts. wt. wax) to 70-110 degrees C, (b) rapidly adding the wax and agitating the mixt. while distilling off H2O in an amt. such that the free H2SO4 content remains >=200 g/l, (c) removing spent oxidising agent, and (d) adding the rest of the chromic acid rapidly to the preoxidised mixt. in one or more stages. In each addn. stage, the mixt. is agitated and H2O is distd. off as in step (b), and spent oxidising agent is removed before the next stage. Compared with prior art processes, the process can be completed in a shorter time with less wax degradation and thus lower chromic acid consumption, using smaller reactors.

Title: Converter maximising use of solar energy - uses rear absorber and heat stores with heat pump
IPC: F24J2/04
Filed: 1979-05-02
Abstract: A typical solar converter circuit for heating installations using solar energy has a rear collector which provides the necessary hot air for driving the heat power machine necessarily a closed circuit.

Abstract: Fibre and/or powder-filled resin-bonded moulds are produced by consolidating but incompletely curing the filler/resin mix in a mould for 2-600 secs around the softening temp., then removing from the mould and fully curing hot. In an example, an apoxide/hardener mixture of 92% glass spheres (dia 3-45 mu m) and 8% 'Grilonit PK 60703" (RTM) has a storage life of at least 18 months at room temp. with a softening point of 70 degrees C (Koflar); its gel time is 10 mins at 120 degrees C and its complete curing time is 15 mins at 150 degrees C. This mix is heated to 70-80 degrees C and quickly placed in a steel mould which is already at 80-100 degrees C). The mould is closed and 30 kp/cm2 pressure is applied. This is reached in about 3 mins. The mould is then opened, the consolidated but only partly cured article is removed without support, and its cure is completed by heating 30 mins at 140-160 degrees C. The final mouldings have a good smooth surface are porous and have excellent mechanical strength and abrasion resistance.

Patent DE-3012528-A1 (DE)
Title: Intelligent teleprinter group terminal - has supervisory circuit obviating continuous repetition of all addresses over inter-terminal control buses
Inventor: FIEBIG HANS-HELMUT DIPL ING
IPC: H04L12/52
Filed: 1980-03-31
Abstract: For a data communication system the address control data derived from a microprocessor (MP) of a connection module (LAM) need not continually be transmitted to the distant receiver station once the connection has been built up and the microprocessor associated with one of the supervisory modules (LPM1, LPM2 etc.) already holds an address for a particular on-going data transmission. In that case, the only data flow that need use up multiplexed bus time, is the communication flow. This prevents the control data bus (CB) from being saturated and provides ample time slots for safe transmission of new address control data for building up or disconnecting a communication channel between two stations. This is realized by comparing addresses generated cyclically by the counter (Cnt) with outgoing addresses already lodged in the supervisory microprocessor module (LMP). The comparison operation takes place in the comparator (Vg1) which produces an enable signal on gate arrays (G8-G9) if a minimum difference number is produced by that comparison. If no address exists in the supervisory module, the outgoing address is fully transmitted.
Patent DE-3013198-A1 (DE)
Title: Automatic sprue extractor in injection moulding - in which opening the mould operates linkages system which grips and removes sprue
Inventor: HELLMANN WOLF-DIETER
IPC: B29C45/17
Filed: 1980-04-03
Abstract: The sprues are removed automatically from injection mouldings by a device with a sprue grip which enters the mould and moves in synchronism with the mould tool. One mould tool has a member plus a vertically moving slide with an extraction lever which carries a sprue extractor and pivots about a horizontal axis against spring pressure; a stud has one end above that pivoting axis and the other end is mounted on the other mould tool. Grip enters mould from above and returns along the same path before moving laterally and laying sprue in extractor, grip therefore occupies minimum space inside the mould, grip continues to be effective even when worn.
